"mmnn's LAMP.

' To-kzll'wltom it may concern:,

Be it known that I,"Funnumo EQBA LD- wIN, a citizen of. the UnitedStates, and a resident of Richmond borough, New York city,'and'S tate of New York, have invented certain new and useful Improvements n Miners Lamps, of which the following a specification.

v :"M invention relates to that class of lamps 10 in w l'lCh acetylene or some other gas is used as the burning fluid; and more particularly lamps of :a size adapted for use mmmes --and on automobiles, bicycles and other ve- .hiclesa Lamps of this classareusuallysublfi-jectedto severe .use and constant shaking and'the burner often becomes clogged or broken. Under these'conditions, it Is I.8C6S-. -sary on the=one hand that the burner be securely held in lace and, on the other 0 hand, that. itmay e easily removed and re;

' -placed. The-object of my invention is to provide a lamp of the above mentioned type with a -burner, orwburner tip, which can be readil removed and replaced without the use o any-tools and yet so firmly held in position that it-cannot be knocked off or jarred off by a: blow or a fall, and cannot be pulled off by'hand. 4

-"With the above principal object in view 80 my inventi n consists'in'the features, details of construction and combinations of parts which "will first be described iinconnection with the accompanying drawing and then particularlypointed out. In the drawings, Figure 1 is a side elevation. partly in section of an acetylene lamp embodying the best form of the invention. Fig. 2 is:an enlarged-sectional view of the burner-tube and reflector shown in Fig. 1, the burner being-partly removed- Fig. 3 is a detail view. of another modification of the invention.

' Referring to the drawings, A indicates a usual form of lamp body, B is aburner tube which in'the present example projects from the lamp body,- D is a reflector and'E is a -burner.--'The.burn'er E is fitted tiglhtly to" the burner tube andheld firmly to t e same 7 by friction onl While the particular mannor inwhich t isfrictional connectionmay be made may be-varied, in the best embodi- 'ment of the invention the'burner is fitted tightly onto or over the endof the burner tube. By-means of this strong frictional connection of the burner with the burner tube, it may be quicklyand readily pushed Specification .1 Letters Patent. Application-filed Kay 16, 1918.

orforced onto the end of the burner tube, and et will hold with sufficient force to .to the'difiiculty of appl ing suflicient for e uniformly around the ed ge of the burner by the fingers only, theburner cannot be removed or withdrawn readily by hand. Therefore suitable means is' provided for pushing the burner from the tube, this means being located between the burner and the. lamp body. In the'best embodiment of the invention this burner-removing means is rotatable with relation to the axis of the burner tube and is so arranged that when rotated it will push the burner from its tube. In the best'form of the invention illustrated in the drawing, the burner-removing means is as follows: The burner; tube is provided with a nut, indicated at C, which has a screw-threaded engagement with the burnertube as indicated at b, and its front edge bears against the rear edge of the-burner. By rotating this nut in the direction ofunscrewing it from the tube, it is caused to travel longitudinally outward and thereby forces the burner ofli the tube.

In the best embodiment of the invention as applied to a lamp having a reflector, the reflector D is connected'to the nut, so that age device or hand-wheel for rotating the nut'C. In order to give a ood bearing of the nut onthe burner, the Iatter may have will be obvious that by this construction, it is only necessary to rotate the nut by the reflector in the direction of unscrewin the nut in order to remove the burner, W. ereupon the nut isscrewed back, and the burner,

essary-may be forced onto the' end of'the tube. It is obvious that these operations may beperformed very quickly, do not re quire any' skill .or delicacy of manipulation and do not necessitate the use of tools. L Another form of leverage device for rotatin the burner-removing means is illustrate in Fig. 3, this consisting of wings D- secured to or forming part of the nut 0, this modification being particularly useful where no reflector is necessary.

'I claim'r I 1. In a lamp,' the combination, with a burner tube, and a burner frictionally held to said tube, of rotatable means mounted satis the requirements of service. Owing its inner edge flanged outward as shown. It

after being cleaned-0r a new one, if necupon the tube and arranged. when rotated in" the said reflector forms.a convenient levertube.

2.-A lamp provided with a, burner frictionally held upon the burner tube, and a 5 lifting nut threaded upon. said tube, and.

adapted to remove said'bui'ner from said tube by the mere unscrewing of the nut.

3. In a lamp, the combination, with a burner-tube, and a burner frictionaily held 10' to said tube, of a burner-removing device' rotatable around said burner-tube, and means arranged to actuate said burner-removing deviee. p

4:. Aiamp proyided with'a'burner fric- 15 tionally held uponthe burner tube, and a re-.

flector provided with a nut threaded upon one direction to push the burner fromthe tube, and adapted to remove said burner 5 from said'tub'e by the mere unscrewing of the nut.
